Update issue with shipment tracking and transit details

Shipped order notices are separate from issue tickets, leaving fulfillment without tracking or ship dates. It writes tracking links and ship dates into the related issue so teams can act the same day.

Overview

When carrier shipment notices land outside your ticket flow, fulfillment and support lose essential tracking and date context. This flow writes tracking links, ship dates, and cost into the matching issue so logistics coordinators can complete handoffs the same day.
